Stackable obstacle

ABSTRACT

A stackable obstacle comprises a base having at least one supporting surface; at least one strip being installed on edges of the supporting surface; an airbag set having at least one airbag; each airbag having at least one combining surface; at least one of the airbag being combined to the supporting surface by the combining surface thereof; edges of each airbag having at least one strip; and a plurality of connecting units for connecting the strip of the base and the strips of the airbags so as to combine the base and airbags.

FIELD OF THE INVENTION

The present invention relates to obstacles, and in particular to a stackable obstacle, wherein by the assembly of the airbags of different shapes, different numbers, or different arrangement, the stackable obstacle has different configurations to suit the requirement in battle game. Thereby no pump is necessary to inflate the stackable obstacle.

BACKGROUND OF THE INVENTION

In battle games (such as paintball games), general, oil tanks, undesired wood boxes, or fences are used as obstacle for shielding the users.

However these prior arts are unsafe for users. Thus air inflation obstacles are developed, which is inflated by an air pump to pump air continuously so that the obstacles are retained in an expansion state.

However the air inflation obstacles need pumps to pump air continuously, cost is high and power is needed. Thereby the shape and size of the air inflation obstacles are determined as they are manufactured.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a stackable obstacle, wherein by the assembly of the airbags of different shapes, different numbers, or different arrangement, the stackable obstacle has different configurations.

To achieve object, the present invention provides a stackable obstacle which comprises a base having at least one supporting surface; at least one strip being installed on edges of the supporting surface; an airbag set having at least one airbag; each airbag having at least one combining surface; at least one of the airbag being combined to the supporting surface by the combining surface thereof; edges of each airbag having at least one strip; and a plurality of connecting units for connecting the strip of the base and the strips of the airbags so as to combine the base and airbags.

Moreover the base includes a cover being a hollow body; a frame placed within the cover; and at least one receiving bag placed in the frame. Each airbag includes a mask being a hollow body; and at least one inflation bag placed within the mask.

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

Referring to FIGS. 1 and 2, the preferred embodiment of the present invention is illustrated. The present invention has the following elements.

A base 10 has a supporting surface 102. Edges of the strip 122 have at least one strip 122. The strip 122 can be arranged based on the shape of the strip 122. For example, if the supporting surface 102 has a rectangular shape, each side of the supporting surface 102 is extended with a strip 122. As shown in FIG. 4, the base 10 further includes a cover 12, a frame 14 in the cover 12 and a receiving bag 16 in the frame 14. The cover 12 has a hollow body. The cover 12 has a zipper for opening and closing the cover 12. When the frame 14 and the receiving bag 16 are placed in the cover 12, the zipper 124 can be closed. The receiving bag 16 can be filled with liquid, stones, sands, or other heavy objects so as to position the base 10. The liquid or stones, or sands in the receiving bag 16 are movable easily.

Referring to FIGS. 5 and 6, an airbag set 20 has at least one airbag 22 (one bags or a plurality of airbags 22) which are placed upon the supporting surface 102. Each airbag 22 of the airbag set 20 has at least one combining surface 202 by which, the airbags 22 are overlapped or are placed on the supporting surface 102 of the base 10. The whole airbag set 20 is assembled on the base 10. Edges of the combining surface 202 of each airbag 22 have at least one strip 242. Likewise, the strip 122 can be arranged with the shape of the combining surface 202.

Each airbag 22 is formed by a mask 24, an inflation bag 26 within the ask 24. The mask 24 is a hollow body. The mask 24 has a zipper 244 so that the mask 24 is openable by the zipper 244. When the inflation bag 26 is placed in the zipper 244. The opening of the mask 24 can be closed. The inflation bag 26 has a valve 262 for inflating air and releasing air. When air is inflated into the bag, the mask 24 is expanded. After inflation, the mask 24 will be expanded. Besides, other than opening the valve 262, the air will not release out. It should be noted, the shape of the airbag 22 is one example of the present invention. In realization of the present invention, other shapes are permissible.

Moreover the strips 122, 242 can be formed with through holes 126, 246, respectively. Thereby when the base 10 is overlapped with the airbags 22. Connecting units 30 pass through the holes 126, 246 so as to fix the airbag set 20 to the base 10, as shown in FIG. 3. The connecting unit 30 may be a beam, a rope, a buckle, a lock, etc.

Other than the connection illustrated in FIG. 3, buckles or sticky strips are usable as a connecting unit 30 for connecting the strips 122, 242.

With reference to FIG. 7, the present invention has a stacking structure. The weight of the base 10 serves to support the airbag set 20 to stand thereupon steadily. Thereby when it is used in a battle game, the present invention is used as a stackable obstacle for shielding the users, or as an obstacle. Thereby the air in the inflation bag 26 will not released out, and thus no air pump is necessary.

Referring to FIGS. 8 and 9, by the assembly of the airbags 22 of different shapes, different numbers, or different arrangement, the stackable obstacle has different configurations.

The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
